Ответы

1. 6 457

• Обоснование: 2 485 + 3 972 = 6 457

2. 7 378

• Обоснование: 9 876 − 2 498 = 7 378

3. 6 944

• Обоснование: 56 × 124 = 6 944

4. 805

• Обоснование: 6 440 ÷ 8 = 805

5. 62,75

• Обоснование: (12 + 47 + 89 + 103) / 4 = 251 / 4 = 62,75

6. 84,2

• Обоснование: (82 + 76 + 88 + 90 + 85) / 5 = 421 / 5 = 84,2

7. 85

• Обоснование: 83 × 6 = 498; сумма известных баллов = 78 + 82 + 90 + 75 + 88 = 413; пропуск = 498 − 413 = 85

8. 21,6

• Обоснование: сумма времен = 18 + 25 + 22 + 19 + 24 = 108; среднее = 108 / 5 = 21,6

9. 43,6

• Обоснование: сумма = 12 + 27 + 34 + 56 + 89 = 218; среднее = 218 / 5 = 43,6

10. 78

• Обоснование: суммарный балл всех 4 учеников = 80 × 4 = 320; известная сумма без пропуска = 67 + 84 + 91 = 242; пропуск = 320 − 242 = 78
